#A10: Cross Border Parity Loop and Kissing Polyominoes

 This is the first day with two puzzles to consider, both new enough that I haven't had too much experience solving either before today. Cross Border Parity Loop feels like what genres like Moon-Sun aspired to be. I can foresee some intriguing connectivity logic depending on how a line navigates around a vertex. At a glance, Kissing Polyominoes looks a bit too similar to Penta Touch, but there are some major distinctions between their solving processes.

Of course, I had to pursue some kind of doppelganger.
